Abstract
Abstract A valve having a disc member which cooperates with the valve seat to perform the valving action, the disc member being characterized by a sail which will be acted upon by fluid in the system to cause rapid and full opening and closing of the valve regardless of the position thereof. The seat and disc members respectively have a complementary frustoconical aperture and a plug portion and the sail is spaced from the seat with the valve in the closed condition.

Claim 1
Independent Claim
323 words
A valve including: a body portion, said body portion defining a chamber and channel defining means extending into said chamber; means in said body portion chamber for supporting a valve seat member, said supporting means including an aperture; a plastic valve seat member having an aperture passing therethrough which defines a frustoconical seating surface, said plastic member further having an outer surface defining portion having an external shape complementary to the shape of the aperture in said supporting means and having a flange extending outwardly from at least one end thereof, said flange having a size and shape sufficient to retain said plastic member in the aperture in saId supporting means; and a disc member cooperating with said plastic member to effect valving action, said disc member having a frustoconical plug portion for engaging said plastic member seating surface, a sail member and a guide post, the diameter of said plug portion of said disc member along the length thereof varying uniformly from a first end of smaller diameter than the largest diameter of said seating surface to a second end of larger diameter than the largest diameter of said seating surface, said sail member extending transversely of the axis of said plug portion from a location along said plug portion of larger diameter than the largest diameter of said seating surface, said guide post extending from the larger diameter end of and co-axially of said plug portion, said guide post extending into and being movable in said channel defining means whereby said disc member is axially movable between a first closed position and an open position, said frustoconical plug engaging said frustoconical seating surface to solely seal said valve in said closed position and said sail being spaced from said plastic member in said closed position, said disc member being free to rotate about its axis under the influence of fluid flowing through said valve with the valve in said open position.
